Intraventricular smooth muscle neoplasia does not usually affect life expectancy if treated in a timely manner, but can affect life expectancy if not treated aggressively. Intraventricular smooth muscle tumors are relatively rare in clinic, characterized by nodular growth of smooth muscle cells in the uterus as well as in the pelvis, which is a kind of benign lesion. However, if left untreated, the condition can progress, affecting areas such as the inferior vena cava and, in severe cases, leading to conditions such as pulmonary embolism. Treatment for intraventricular smooth muscle tumors usually involves surgery to remove the excess nodule-like tissue. When the disease of intraventricular smooth muscle tumor appears, it is recommended to go to the hospital in time, and under the guidance of the doctor to carry out standardized treatment, so as not to delay the condition.
